Plants such as Pinus, Juniparus, Pyrus and Vitis metabolize nitrogen oxides

Answer

### Step-by-Step Solution:

1. **Understanding Metabolism**:
- Metabolism refers to the chemical processes that occur within a living organism to maintain life. It involves the conversion of food into energy, which is essential for growth and other vital functions.

2. **Identifying the Plants**:
- The plants mentioned in the question are Pinus (pine trees), Juniperus (junipers), Pyrus (pears), and Vitis (grapes). These are all types of plants that can be found in various environments.

3. **Role of Nitrogen Oxides**:
- Nitrogen oxides (NOx) are pollutants that can be metabolized by certain plants. Some plants have the ability to absorb these gases and utilize them in their metabolic processes.

4. **Metabolism of Nitrogen Oxides**:
- The plants listed (Pinus, Juniperus, Pyrus, and Vitis) can take nitrogen oxides as a part of their nutrient intake. They metabolize these compounds to convert them into energy, which supports their growth.

5. **Conclusion**:
- Since these plants can indeed metabolize nitrogen oxides, the statement in the question is **true**.

### Final Answer:
The statement that plants such as Pinus, Juniperus, Pyrus, and Vitis metabolize nitrogen oxides is **true**.
